Ok, i made a frankenstein monster speaker with various bits and bobs i found round the house and crap from china. Thing is, it works. But its very obviously cutting out the bass. I have it set correct on amp to play high mid and bass. Ive played with equilisers. I just cant seem to coax it out! My biggest problem is power, as its d/c being run from a/c theres choke points with power delivery. And im vastly out my skill set now, its frustrating as my little bose speaker is doing a better job that my "high power" speaker. Here is a list of the components, vibe k series speakers, https://www.sonicelectronix.com/item_37532_VIBE-Audio-SEK50-sek50v3.html Juice ja492 amp https://www.caraudiocentre.co.uk/product_m-juice-ja492_p-32823.htm Mp3 decoder https://es.aliexpress.com/item/Bluetooth-4-0-Audio-MP3-Player-Decoder-Board-Loss less-Music-Recorder-APE-FLAC-FM-SD-MMC/32830510737.htm Power, 24v 10A dc power supply.
